RFLPs for laminin B2 (LAMB2) are reported. These RFLPs were used to study the linkage relationships of LAMB2 to four other genes on lq: Duffy (FY), renin (REN), decay accelerating factor (DAF), and complement receptor 2 (CR2). Multipoint linkage analysis placed LAMB2 between FY and the cluster including REN, DAF, and CR2. This provides a useful bridging polymorphic marker on lq and establishes significant linkage of LAMB2 to FY (θ = 0.23, z = 3.85) and REN (θ = 0.17, z = 4.88).
